Patent CA-2117665-A1 (CA)
Title: Printing unit for a web-fed printing machine
Inventor: LAPP JOACHIM A H
IPC: B41F5/16
Filed: 1994-09-08
Abstract: The printing unit has two cooperating cylinders (1, 4) which form the printing nip and which have printing saddles (2, 5) separated by cylinder pits (3, 6). The paper web (7) passing through the printing nip is transported in the pilgrim-step mode, in order to print formats adjoining one another. The two cylinders (1, 4) are angularly adjustable relative to one another, in respect of the position of their printing saddles (2, 5) cooperating in the printing nip, in a manner offset by the amount of a circumferential distance which is approximately equal to the difference between the circumferential length (S) of a printing saddle and the circumferential length (B) of a printing image. The printing zone is therefore only approximately as large as the printing image, and the print-free zone available for retracting the paper web is correspondingly enlarged.

Patent CA-2124408-A1 (CA)
Inventor: EKMAN THURE
IPC: F16L37/40
Filed: 1994-05-26
Abstract: ABSTRACT A quick coupling component (2) comprises a valve member (1) for a main flow (4). Arranged in the valve member  is  a pressure reduction member with pressure reduction channel  (7).  The pressure reduction member comprises a shut-off element (8) which is arranged in the channel and which can bear against a seat  (9) and is lifted by an activation member (13) counter to the action of a spring (10). The surface of the seat has a degree of fineness which corresponds to a great extent with the degree of fineness of the shut-off element. The latter has a hardness which substantially exceeds the hardness of the seat material. An inherent elasticity of the seat material  contributes  to  the  sealing  function of  the element against the seat in the closed position of the element.          It  is  proposed  that  Figure  1  should  accompany  the abstract.
Patent CA-2127240-A1 (CA)
Title: Hockey Goaltender's Blocker with Angled Upper Area
Inventor: WAGNER STEVEN G
IPC: A63B71/14
Filed: 1994-06-30
Abstract: The goaltender's blocker has an angled upper area, with the inside edge of the blocker being raised more than the outside edge.  The angled upper area thus angles outwardly away from the plane of the rest of the blocking pad, and also towards the outside edge.  One result of this configuration is that when the goaltender is in the usual upright position with the blocker oriented generally upright, a puck which hits the angled portion of the blocker will be deflected outwardly, i.e. toward the corner of the hockey rink, instead of rebounding in front of the net where a goal may be scored by an offensive player.
Patent CA-2130032-A1 (CA)
Title: Cleaning method for heat exchangers
Inventor: BAUM ALLEN J
IPC: B08B9/02
Filed: 1994-08-12
Abstract: ABSTRACT OF THE DISCLOSURE         An improved method for cleaning heat exchangers, wherein a first liquid containing a cleaning agent is used to remove substantially all of the accumulated sludge and deposits from the surfaces of the heat exchanger, and a second liquid containing a cleaning agent is used to remove deposits from the crevice regions of the heat exchanger. The concentration of cleaning agent in the second liquid and/or the duration of exposure for the second liquid are preferably greater than those of the first liquid, because the risk of corrosion is reduced as a result of a lower concentration of ferric ions in the second liquid.  Fur-thermore, improved crevice region cleaning is obtained with the second liquid because the available cleaning agent is not depleted by the large volume of sludge and deposits removed by the first liquid.   Mechanical cleaning tech-niques such as pressure pulse cleaning may be utilized with either or both of the cleaning liquids.  Additional liquids may be  introduced  into the heat exchanger to provide further cleaning action or to facilitate flushing of the previous cleaning liquids.

Filed: 1994-08-23
Abstract: Invention patent for a "FOUNDATION SYSTEM FOR      TENSION LEG PLATFORMS".        A foundation system for tension leg platforms without use of foundation templates, wherein each tendon (5) is directly connected to a socket (9) inside the pile (8), said piles (8) being positioned for driving purposes by means of a pile-driving template (10) which is employed as a spacing device is described. The pile-driving template (10) is positioned with the aid of pins (11) that slot into guides (7) built into the well template (6). After the groups of piles (8) needed to anchor a corner of the platform (1) have been driven in, the pile-driving template (10) is withdrawn and repositioned so as to enable the piles for the other group of legs to be driven; this process continues until all of the pile-driving is finished. Alternatively one single pile-driving template (16) may be employed to guide the driving of all the piles (8) thus doing away with the need to reposition the template every time. The bottom ends (14) of the piles are conical in shape, and after the piles have been driven they are filled up with some high specific gravity material.

Title: Shock absorbing and impact absorbing device
Inventor: LAI WAI K
IPC: F16F9/02
Filed: 1994-11-01
Abstract: Shock absorber for suspension on motor vehicles or bikes and impact absorber for bumper on motor vehicles to absorb impact in collision are provided to operate by mechanical means, when the absorber hits a bump or impact, the energy drives the moveable parts of the absorber to cause an increase of air pressure and vacuum respectively in the two isolated adjacent compartments inside its hollow cylindrical body. The increase of air pressure and vacuum are both directly proportional to the bump or impact energized to the absorber. The increased air pressure and vacuum act as buffer material producing damping effect when it acts as a shock absorber and impact absorbing effect when it acts as an impact absorber.

Title: Improved Collet and Method for Optimizing Gripping Action Thereof
Inventor: KANAAN ROGER J
IPC: G01N3/22
Filed: 1995-01-04
Abstract: The present invention relates to a method and process for manufacturing an improved machine tool collet. The invention further relates to an improved machine tool collet having design parameters optimized to maximize the gripping strength of the collet. The collet according to the invention is of the type having a plurality of gripping jaws spaced around a common longitudinal axis with resilient material between the gripping jaws. The method includes calculating the total torque generated on a bar passing through the collet for a given collet configuration having predetermined design parameters.

Title: Stereophonic reproduction method and apparatus
Inventor: PINEAU JOSEPH E M
IPC: H04R5/027
Filed: 1994-05-06
Abstract: A method and apparatus for stereophonic reproduction uses conventional left and right stereophonic signals to energize a point source transducer in a complementary manner. The resultant interference sound pattern is interpreted by the brain of a listener to enable the listener to experience stereophonic hearing in a wide region surrounding the transducer, not just in the region of the plane of symmetry. A point source transducer may be simulated by a plurality of transducers positioned with the spacing therebetween less than a determinable maximum distance. While conventional stereophonic signals may be employed in the reproduction of sound, improved reproduction is obtained by producing the signals by recording sound with a pair of microphones arranged with the apogees of their respective field of polar response patterns facing substantially at 180° to one another.

Abstract: A method and system for customizing the protocol by which two or more users of a network communicate.   The system utilizes  a  database  containing  customer  transaction profiles.  These profiles contain definitions of how input and output messages should be formatted, and instructions on how the  flow of communication should be conducted.   A network user's customer transaction profile can be readily altered by editing the database.  In a preferred embodiment, a front end system in the network maintains the database and performs  all  of  the  functions  necessary  to  provide customized  communication.    In  this  manner,  a  network operator can provide customized protocols to each network subscriber quickly and without asking that subscriber to install special equipment or software.
